“…However, in the literature, some MRI features have been reported that could raise the suspicion of CM of the sellar region. Indeed, the presence of a hyperintense signal in T2 sequences associated with delayed centripetal contrast enhancement on MRI images could raise suspicion ( 39 ). Due to the high vascularity and profuse bleeding of the lesion during surgical removal, a subtotal resection to obtain neurovascular decompression followed by radiotherapy might be considered the most effective strategy of treatment.…”

IntroductionThe sellar region and its boundaries represent a challenging area, harboring a variety of tissues of different linings. Therefore, a variety of diseases can arise or involve in this area (i.e., neoplastic or not). A total of three challenging cases of “chameleon” sellar lesions treated via EEA were described, and the lesions mimicked radiological features of common sellar masses such as craniopharyngiomas and/or pituitary adenomas, and we also report a literature review of similar cases.MethodsA retrospective analysis of three primary cases was conducted at the Università degli Studi di Napoli Federico II, Naples, Italy. Clinical information, radiological examinations, and pathology reports were illustrated.ResultsA total of three cases of so-called “chameleon” sellar lesions comprising two men and one woman were reported. Based on the intraoperative finding and pathological examination, we noticed that case 1 had suprasellar glioblastoma, case 2 had a primary neuroendocrine tumor, and case 3 had cavernous malformation.ConclusionNeurosurgeons should consider “unexpected” lesions of the sellar/suprasellar region in the preoperative differential diagnosis. A multidisciplinary approach with the collaboration of neurosurgeons, neuroradiologists, and pathologists plays a fundamental role. The recognition of unusual sellar lesions can help surgeons with better preoperative planning; so an endoscopic endonasal approach may represent a valid surgical technique to obtain decompression of the optic apparatus and vascular structures and finally a pathological diagnosis.

Cavernous venous malformations of the cavernous sinus are rare, benign tumors that account for 2%‐3% of all cavernous sinus lesions. An accurate pretreatment diagnosis is important due to the highly vascular nature of these lesions and the risk of major intraoperative hemorrhage. A shifting preference toward radiosurgery as a primary treatment, increasingly without a pretreatment biopsy, further underscores the need for an accurate imaging diagnosis. The aim of this pictorial review is to illustrate the imaging findings of cavernous sinus venous malformations on CT and MR imaging, the use of red blood cell scintigraphy as an adjunct imaging technique, relevant differential diagnoses, and management.Learning Objective: To describe the main imaging features of cavernous sinus venous malformations using CT, MR imaging, and red blood cell scintigraphy to differentiate them from other common lesions of the cavernous sinus

Cavernous angiomas (CAs) are benign vascular malformations predominantly seen in the brain parenchyma and therefore referred to as intra-axial. Extra-axial dural-based cavernous angiomas, on the other hand, are rare vascular lesions found outside of the brain parenchyma. They occur in the middle fossa and may be easily misdiagnosed as meningiomas due to their extra-axial location. In addition, CAs that are located outside the middle fossa, such as in the convexity, have a better prognosis since they are more surgically accessible. Surgical resection is the main treatment of choice in CAs. However, other options, such as embolization and radiotherapy, may also be considered therapeutic choices or additive treatment options. The pathogenesis of CA and the involvement of other factors (genetics or environmental factors) are still unknown and require further investigation. We are presenting a young man who presented for evaluation of seizure-like events without any family history of neurologic conditions. The physical examination was unremarkable except for a slightly antalgic gait. Imaging studies showed an extra-axial left tentorial mass suggestive of a meningioma, hemangiopericytoma, or other extra-axial lesions. The lesion was resected where its vascular nature was mentioned initially, and the histology proved the diagnosis of cavernous angioma. Here we give an overview of the known pathogenesis, causes, clinical features, and diagnostic and therapeutic options in CA. Better knowledge about CA, its causes, clinical features, and treatment options would help clinicians in early diagnosis and patient management.
